水下分流河道砂体地震储层预测及在水平井实施中的应用
|
摘要
B油田主要油藏类型为在复杂断块、断鼻构造背景下形成的岩性、构造-岩性油气藏,储层发育程度低,以水下分流河道砂体为主要储层类型,单砂体厚度薄,储层横向变化快,砂体叠合程度差,纵向上油气水关系复杂。针对上述开发难点,在精细层位标定的基础上,采用稀疏脉冲反演方法和属性综合分析技术进行储层预测,采用地震地质相结合进行综合分析的思路,结合测井相、沉积相、地震响应分析结果,将砂体的地球物理响应特征与地质认识相结合,正确认识水下分流河道砂体地震响应与地质模式的关系,成功的指导了水下分流河道砂体的水平井部署实施,取得了较好的应用效果。
The main reservoir types of B oilfield are lithologic and structure-lithologic reservoir based on complex faulted-blocks and faulted-nose structures, with the characteristics of low degree of reservoir development, small thickness of single sand body, quick lateral variation, poor degree of superimposition of sand bodies and complex relationship of oil-gas-water in vertical direction. Aiming at the problems mentioned above, on the basis of fine horizon calibration, the method of sparse impulse inversion combined with attributes synthetic analysis has been adopted to carry out reservoir prediction. Under the guidance of synthetic analysis of seismic data and geology, in combination with logging facies, sedimentary facies, analysis results of seismic correspondence, the understandings of geophysical correspondence and the geology have been both considered so as to make clear the relationship between underwater distributary channel and geologic mode, as well as successfully provide a good reference for horizontal well design of underwater distributary channel and has achieved better application effect.
